Guild Wars 2

There’s never gonna be a situation where the enemy NPC can’t reach the player, if they’re both underwater, since the enemy can go any direction they need to when underwater. So please turn off invulnerability when players are underwater and fighting underwater enemies. If someone tries fighting land based enemies from underwater or vice-versa, that’s a different story, since there are some terrestrial-only enemies and aquatic-only enemies. But when enemies go invulnerable, underwater, for no reason, it gets very annoying and frustrating. So please turn off invulnerability when both combatants are underwater.

Invulnerability just needs to go.

When an enemy can’t reach you, it should move out of your reach. Fixed.
